Answer:
It can be almost ANYTHING but 2nd and 3rd length have to be bigger than 4
Step-by-step explanation:
You got the 1st length of the triangle, which is 4. And then we can "guess" what those length are. But whatever the length is, it won't be 0, and 2 length add up together will not be equal or less than 4, if you don't understand, draw it on the paper and you will get a straight line.
Answer:
0.63091482649
Step-by-step explanation:
Total number of students surveyed = 200
Number of male students = 80
Number of female students = 200 - 80 = 120
Number of brown eyed male students = 60
Probability of a brown eyed male student = 60 / 80 = 0.75.
Since, <span>eye color and gender are independent, this means that eye color is not affected by the gender. Thus, we expect a similar probability of brown eye for female as we had for male.
Let the number expected of brown eyed females be x, then x / 120 = 0.75.
Thus, x = 120(0.75) = 90.
Therefore, the number female students surveyed expected to be brown eyed is 90.</span>
